If you get this error message about not being able to start the COM server then you're mixing roles (if your VMs run as a regular user without special privileges then you're running the command as Admin or vice versa)... otherwise you should always get this error and that's a sign of a broken install.

Sorry my mistake. I ran cmd as Administrator. Did the command again and it worked. This command fixes the problem. It also works when I increase the memory.
